Is it better to have a built in antenna or an external antenna in a router?

Theoretically, it's about the same.,But the built-in antenna,The advantage is that there is no one that grows out of the uh,It may be easier and more convenient to place it.,If it's external, the signal may be a little better.,After all, you can adjust the angle if you can pull the wire.,You may be in the room location.,You may need to adjust the angle.,In this way, it's better for this signal.,But it's a problem to place 100% of the world.,For example, it's a weak current box.。

It may not be very convenient inside. And it's ugly, right?,This kind of antenna router,But in general, it's almost the same.,There's no need to be too entangled.。

Of course, an external antenna would be better, because it would have a stronger signal. Nowadays, most of the routers with external antennas are chosen. Of course, it also depends on the performance of the router itself, the higher the performance, the more the range covered by the router will be.

It's the same in theory. It's just that the power is different. Comparatively speaking, the external signal is stronger.

Built-in antennas are more expensive.

Theoretically, there is no difference, whether the wifi signal is strong or not mainly depends on the router power, the number of antennas, the antenna material, the antenna length, etc. The router is more stable with ASUS, Huawei, TP and other brands.

The broadband router integrates the functions of router, firewall, bandwidth control and management in a compact box, with the characteristics of fast ability, flexible network management and rich network status. Many users buy wireless routers.

It's easy to be confused by the appearance, and there are more antennas than the other!Below I bring the router misunderstanding answers, come and take a look.

The external antenna must be better than the built-in

The built-in antenna of the wireless router is actually similar to the external signal, but the antenna is placed inside the device, which is safer and less likely to be damaged, and more space-saving.

More and more manufacturers are starting to produce wireless routers with built-in antennas.

Therefore, in some cases, a wireless router with a built-in antenna is better than an external one.

Since the router is a key device in the network, various security risks exist in the network.

The router must have the following security features:

1) Reliability and line safety Reliability requirements are put forward for fault recovery and load capacity. For routers, reliability is mainly reflected in interface failures and increased network traffic, for which backup is one of the indispensable means of routers. When the primary interface fails, the backup interface is automatically put into operation to ensure the normal operation of the network.

When network traffic increases, the backup interface can take on the task of load balancing.

2) Identity authentication in the router mainly includes the identity authentication when accessing the router, the identity authentication of the peer router, and the identity authentication of routing information.

3) Access controlFor the access control of the router, the password needs to be protected at different levels. There are IP address based on that.

and user-based access control.

4) When the information is hidden and the peer communicates, it is not necessary to communicate with the real identity. Through address translation, you can hide the address in the network and only access the external network in the form of a public address. Except for connections initiated by the internal network first, users outside the network cannot directly access on-network resources through address translation.

5) Data encryption.

In order to avoid information leakage caused by data eavesdropping, it is necessary to encrypt the transmitted information, and only the peer communicating with it can decrypt the ciphertext. By encrypting the packets sent by the router, the privacy and integrity of the data and the authenticity of the packets can be ensured even when they are transmitted over the Internet.

6) Attack detection and prevention.

As an interface device to the outside of the internal network, the router is the first target for attackers to enter the internal network. If the router does not provide attack detection and prevention, it is also a bridge for attackers to enter the internal network. Providing attack detection on the router can prevent a subset of attacks.

7) Safety management.

There are three differences between the built-in single-antenna wireless network card and the dual-antenna wireless network card: one. physical hardware differences; Two. The difference between the dead ends of sending and receiving; Three. Difference in sending and receiving efficiency.

1.physical hardware differences; It is obvious that there is a difference in the number of antennas and two antennas.

2.The difference between the dead ends of sending and receiving; The blind spot of transmission and reception refers to the physical characteristics of the best transmission and reception intensity and sensitivity of the wireless network sparrow pants stuck in the transmission and reception process.

After a certain distance, the physical emission intensity and reception sensitivity are obvious with the different angles of the antenna. The single antenna is prone to receive dead angles (signal strength becomes 0), while dual antennas can overcome the receiving dead angles due to two receiving angles.

3.Difference in sending and receiving efficiency. This means that under the premise of the same transmitting intensity and receiving sensitivity, a single antenna can only maintain one transmitting and receiving angle (single state), and the transceiver efficiency is low, due to the existence of dead angles between transmitting and receiving.

The dual antennas can maintain two transmitting and receiving angles (dual state), which is not easy to produce a dead angle of transmission and receiving, thus improving the transmission and receiving efficiency. The actual effect also proves that the dual antenna is farther than the single antenna sending and receiving distance of the same power wireless network card.

1. The wireless router should be placed in an open place, and the antenna should be placed vertically;

2. If it is placed in the middle of the whole room, there will be no problem with the signal of other rooms;

3. If it is placed near a window, then there is absolutely no pressure on the signal near other windows in the same direction;

The wireless router with a power of 4,150m is enough for the family, and it is not recommended to use the 300m one, as the radiation is harmful;

5. There is a setting about power in the router settings, and you can adjust it to the maximum. This option is generally found in "Wireless Management - Advanced Settings - Power Settings";

6. The wireless router can penetrate up to 2 walls, and the vertical effect is better; As a result, the neighbors on the upper and lower floors of your home receive better signals than the same floor;

In view of the above, observe for yourself to know how to achieve the strongest signal!
